Thediaphragm valve has a structure in which a diaphragm piece and a piece holder for holding a conical piece are coupled in a valve housing, the outer peripheral edge of an inner diameter opening of thediaphragm is clamped by the piece holder and the diaphragm piece, the diaphragm piece is held by a bonnet so as to be capable of moving up and down, and the bonnet and the outer peripheral edge of thediaphragm are clamped so that the piece is suspended from the diaphragm. The diaphragm valve is provided with a conical sealing part formed on the conical surface of the piece and a cut-off valve seat part formed on the primary side opening edge of the valve box, reaction products generated on the conical sealing part are cut off through sliding movement of the piece, and the conical sealing partis sealed through the cut-off valve seat part.

The present invention addresses the problem of providing a plastic cell that maintains conductivity without losing sealability even when a plastic substrate is deformed into a free shape having an uneven surface or a curved surface, and a method for manufacturing the plastic cell. A plastic cell according to the present invention has, in this order: a first plastic substrate; a first transparent conductive layer; a fluid layer; a second transparent conductive layer; and a second plastic substrate. The plastic cell also has sealing part that includes a portion of the first plastic substrate orthe second plastic substrate, wherein the portion of the first plastic substrate or the second plastic substrate is deformed and seals the fluid layer. The sealing part has: a first sealing section that disconnects passage of electric current between the first transparent conductive layer and the second transparent conductive layer; and a second sealing section that allows passage of electric current to either the first transparent conductive layer or the second transparent conductive layer.

A flow spinning device, comprises a revolving cup housing in negative pressure, and a rotation spinning cup is in the housing. To reveal the spinning cup, a swing housing can swing from the revolving cup is located, and is close to the revolving cup housing. The spinning cup stops rotating by a brake lever when the swing housing is closed. A interlock device is connected to the brake lever, to swing the make position of outer cover and remove the interlocking by way of handling the brake lever. A guiding parts is located on the swing housing, and plays the direction face of fixed revolving cup stopper application position on its subsides when the swing of swing outer cover is leaned on and is lain in the brake lever to one. Besides the interlock, an interlock which is drived alone is still located. So that the revolving cup is sealing well, and avoid the unexpected operation.

The invention provides a cable pipeline sealing module. The cable pipeline sealing module comprises a base material, a rubber diaphragm, an expansion unit material and a blockage core rod. The cable pipeline sealing module in the invention has the performances that: (1), redundancy design is supported; therefore, a sealing system using the sealing module has the expansion capability in a design interval; and an expansion space can be reserved for cable or pipeline upgrading and reconstruction; (2), installation is simple and convenient; and a convenient condition is provided for later maintenance and cable inspection; (3), the sealing performance cannot be reduced by change of the cable or pipeline size tolerance; (4), the module has excellent air aging or oil resisting performance; and (5), the sealing performance when a cable or pipeline passes through a container in a low-voltage container can be improved; and the module can work in a high-temperature and ozone environment for a long time.

Seal ring provided between rotating portion and fixed portion in rotating machine of steam turbine and the like is improved to carry out predetermined movement accurately so as not to cause deterioration of sealing performance. Seal ring is split into upper, lower, right side and left side seal ring pieces 1a, 1b, 1c, 1d, contacting slidably with each other via split planes 3a, 3b, 3c, 3d with spaces 9a, 9b, 9c, 9d being formed in the respective split planes. Springs 4a, 4b, 4c, 4d are interposed in the spaces 9a to 9d for activation in upward and downward directions. The upper and lower seal ring pieces 1a, 1b are engaged with seal ring guides 5a, 5b and 6a, 6b and the right side and left side seal ring pieces 1c, 1d are engaged with seal ring guides 7, 8 so that all of the seal ring pieces 1a to 1d are slidable in the upward and downward directions. Further, on the respective tips of the seal ring guides 5a, 5b and 6a, 6b, spaces 10a, 10b of the upper seal ring piece 1a and spaces 10c, 10d of the lower seal ring piece 1b are formed and springs 11a, 11b, 11e, 11d are provided in the spaces 10a to 10d for activation in the upward and downward directions. The respective seal ring pieces are prevented from skirmishing with each other and the upper and lower seal ring pieces move toward the inner side at the time of load so as to make narrower the clearances between seal fins 2a, 2b and corresponding rotor surface.
